GUIUtility.ScreenToGUIPoint
static function ScreenToGUIPoint(screenPoint: Vector2): Vector2;
static Vector2 ScreenToGUIPoint(Vector2 screenPoint);
static def ScreenToGUIPoint(screenPoint as Vector2) as Vector2
Description

Convert a point from screen space to GUI position.

Used for reconverting values calculated from GUIToScreenPoint

Note: In Unity the screen space y coordinate varies from zero at the top edge of the window to a maximum at the bottom edge of the window. This is different from what you might expect.

See Also: GUIUtility.GUIToScreenPoint.
	// Check the difference between the mouse position (Screen) and
	// the converted GUI positions because of the group.
